IM PROVEMENT IN WINIDMILLS.

Specication forming part of Letters Patent No. 217,147, dated July l, 1879; application led March 5, 1879.

To all whom it may concern:

Be it known that I, JOHN J. REED, of Lyons city, in Clinton county, State of Iowa, have invented certain new and useful Improvements in Windmills, whichimprovements are fully set forih in the following specification and accompanying drawings, in which- Figure l is a plan or top view. Fig. 2 is a longitudinal section of the brake; Fig. 3, cross-m In the drawings, A is the spider of windwheel; B, a gear-wheel attached to spider A. Cis a friction-pinion hung on a swinging frame, and meshes into gear-wheelB when in action. G shows sections of friction-pinion on line D, Fig. 2. H shows section of friction-pinion on line F, Fig. 2. J represents the vane or tail; K, the swinging frame that carries the friction-pinion C; L, a cord or chain that is attached to vane at O2, runs through and over sheave at P, thence over [sheave at O, thence to ground, for convenience of turning mill out of wind by hand; M, a short arm attached to the vane, which, when it is moved either by wind or by hand, engages a piece fastened to the swinging frame K, marked az, and as the vane continues to move around arm M will force the frame K aroundfcarrying with it the friction-pinion C, which meshes into the gear B and effectually stops the wheel A 5 N, a stop to vane J, and is arranged to keep the wheel A and vane J at the desired angle in relation to each other and the wind.

R represents the bracket-frame of the mill, and I usually make it of cast-iron. S is a perpendicular bolt or rod passing through two arms of frame R, and around which the vane J and swinging frame K move as a center. T and V areanti-friction rollers in slots in the arms of vane J, to reduce the friction as the vane moves up and down on rod S 5 W, a hingejoint. Y represents the pitman to operate the pump; Z, a roller on vane J 5 Z2, an adjustable inclined way for roller Z to travel on; W2, an adjustable joint for brace V2; T2, a small weight to draw the pinion C away from gear B.

Operation: To bring the wheel out of the wind by hand, grasp the rope or chain L, and by drawing down on it the vane J is drawn around and is raised or carried up the inclined plane or way Z2, the vane J being always in a level position, and as it moves around the arm M forces the frame K, carrying the frictionpinion O forward till it meshes into the gearwheel B and holds the wind-wheel stationary.

It will be seen by Fig. 2 how the frictionpinion C is arranged. A spiral spring forces the `pinion O against a collar, and by turning nut at end of the bolt the frictioncan be adjusted.

When it is desired-to let the wheel into the wind, loosen the cord or chain L, and the weight of the vane will cause it to move down on the inclined way Z2, swinging on rod S till it is stopped by a rubber cushion at N.

When the wind blows very hard the action of the wheel is to force the vane into the wind 5 but the vane4 holds its position infrelation to the wind, and the wheel turns the bracketframe R, the vane rides upon the inclined way,

engages the frame K, same as was done by hauling on the cord or chain L.

Now, it will be observed that the inclination of the way Z2 will determine the movement of the vane, for if it is quite or nearly level aless amount of wind will move it than if it is set quite steep. For adjusting the inclination of this way, the foot of the brace V2 is slotted, so that it can be moved on a bolt. This foot is also corrugated, and a washer, which is also corrugated, matches the brace. Now, by placing the parts together and tightening the nut, the brace will hold the way at the desired angle.

I have near the top end of way a slight curve, so when the force of the wind is lessened the movement of the vane down the plane will be aided in its movement by the roller Z, which will start down this curve quite easily.

When the vane J descends the way Z2 the weight T2 will draw the pinion C away from the gear B, it being` hung midway-ou admin that is attached to frame K and end of way Z?.

The brace V3 is hinged on the bracket-frame R, and is iitted close to inclined Way Z2, and keeps it from turning.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a Windmill, the vane or tail J, provided with the anti-friction rollers T, V, and Z, when arranged substantially as and for the purpose speeied.

2. In a Windmill, the adjustable inclined Way Z2, provided with the hinged braces V2 andVfVsnbstantially as and for the purpose Snecli'di 3. In a windmill, the friction-brake pinion U, in combination with the gear-wheel Band the tai1-vane, substantially as and for the purposeset forth.

In'v testimony whereof I have hereunto set .my hand this 22d day of February, A. D. 1879,
